INFORMATION PROCESSING APPARATUS, CONTROL CIRCUIT, AND CONTROL METHOD

摘要

An information processing apparatus includes a storage device that includes a plurality of storage areas, and a processor coupled to the storage device. The processor executes a process including: first counting, among blocks each including a plurality of storage areas included in the storage device, number of transfer candidate blocks including the storage areas in which written data is invalidated; second counting, among the blocks, number of reserve blocks in which no data is written in the respective storage areas; determining whether transfer processing is to be started, in accordance with a result of comparing a count value of the first counting with a count value of the second counting; and transferring only valid data written in the respective storage areas of the transfer candidate block to the reserve block when it is determined that the transfer processing is to be started.

1. An information processing apparatus, comprising:
a storage device that includes a plurality of storage areas; and a processor coupled to the storage device, wherein the processor executes a process comprising: first counting, among blocks each including a plurality of storage areas included in the storage device, number of transfer candidate blocks including the storage areas in which written data is invalidated; second counting, among the blocks, number of reserve blocks in which no data is written in the respective storage areas; determining whether transfer processing is to be started in which data is transferred from a transfer candidate block to a reserve block, in accordance with a result of comparing a count value of the first counting with a count value of the second counting; and transferring only valid data among data written in the respective storage areas of the transfer candidate block to the reserve block when it is determined that the transfer processing is to be started.
